Sophia E. Hayes and her research group at Washington University in St. Louis depend on liquid helium to cool the magnets in their nuclear magnetic resonance instruments to a superconducting temperature of 4 K. Her chemistry lab, which in part uses the instruments to study the structure of metal oxide clusters, runs through an average of 157 L of liquid helium every month.

Hayes has watched liquid helium prices balloon from . . .
